VIBRATO-TRAGTION TABLE.

Specification of Letters Patent.

Patented July 2%, 1917.

Application filed May 16, 1916. Serial No. 97,848.

To all whom it may concern:

Be it known that I, HARRY GOLDMAN, a citizen of the United States, and a resident of the city of New York and State of New ork, have invented a new Improved Vibrato-Traction Table.

This invention relates to the form of tables used for stretching patients as in the chiropractic treatment where the person is placed flat upon the table, the upper limbs are strapped to one end of the table while the lower limbs are strapped to a reciproeating member at the other end of the table. This causes an alternate stretching and relaxation of the body, particularly of the spinal column. The object of this invention is to provide a table of neat and simple construction, readily adjustable in a longitudinal and a vertical direction while the patient is lying on the table, thereby adapting it for the use of persons of various sizes and shapes.

One of the important features of my table is that the base is made of one piece, while the upper portion is constructed in two parts, one being fixed against longitudinal movement but capable of vertical adjustment while the other part is adapted for longitudinal and vertical adjustments. Another important improvementin my device is that the horizontal bars 31 to which the traction straps are attached are provided with a recess to receive the straps and thereby keep them in. place as the tension is alternately applied and released. Another feature of my device is that the vertical bars to which the horizontal bars 31 are attached, are square in cross section instead of round as in most of the tables in use. The horizontal bars are thereby fixed against rotation.

Other improvements and features of my device will be apparent from the detailed description and the accompanying drawings forming a part of this specification, in which similar numerals refer to similar parts in all the views and in which; Figure l is a plan view of the table; Fig. 2 is a sectional plan taken on line 2-2 of Fig. 3; Fig. 3, is a sectional elevation taken on line 3-3 of Fig. 2; Fig. 4 is a partial section taken on line 4L4 of Fig. 3; Fig. 5 is an elevation of the support for the horizontal traction bar looking in the direction of line 55 of Fig. 3; Fig. 6 is a partial section on line 6-6 of Fig. 3; Fig. 7 is a large scale detail showing the arrangement for vertical adjustment at one of the posts; Fig. 8 is a section on line 88 of Fig. 3; Fig. 9 is a section on line 9-9 of Fig. 3: and Fig. 10 is a partial elevation looking in the direction of line 101O of Fig. 6.

Referring to the drawings, the principal parts of my device consist of the base 1 and the two independent tables 2 and 3. The two legs 4 of the table 2 are securely fixed to the base 1 and are provided at their upper ends with metal pieces 6 having suitable grooves to receive the longitudinal boards 5 of the upper frame which are pivotally connected to the metal pieces (3, while the legs 7 are fixed at the other end of the boards 5. The pieces 8 preferably made of metal are provided with a slot 9 and are securely fixed at the bottom of the legs 7. The rod 10 running for the full width of the base 1 is held in place by passing through the slots 9 and engages with the two racks 11 fixed to the sides of the base 1. The rod 10 is also aided to stay in engagement with the rack 11 by the steel spring 12, as is clearly shown in Fig. 7. The horizontal rod 14, provided with two levers 15, one on each side of the table, is rotatably fixed near the top of the table, preferably to the legs 7. The rods 13 fixed to the rods 14 are adapted to be brought in contact with the rod 10 and are limited in their rotation to the right by the bar 16.

It will now be evident that if the right hand end of the table 2 be lifted upwardly, the rod 10 will slide along the under side of the adjacent tooth of the rack 11 and will pass over the tooth and engage with its upper surface. This will increase the inclination of the table 2 with the horizontal. If it be desired to lower the right end of the table, it can be accomplished by pulling on the arms or levers 15 upwardly, thereby bringing the rods 13 against the rod 10, and then lifting the end of the table slightly. This will cause the bar 10 to disengage from the tooth it is in contact with and engage with the lower tooth.

The table 3 is slidably mounted on the base 1, in addition to the adjustment for tilting similar to that for table 2. The two legs 18 are securely fastened to the boards 20 and 21, which, together with the inclined board 24, form the bottom frame of the table 3. The legs 18 are provided at their rod 10.

pull against the bar 31.

upper ends with metal pieces 6 similar to the pieces 6 on table 2 and to which the longitudinal sides 19 of the upper frame are pivotally connected. The two legs 17, securely fixed to the upper frame, are provided at the bottom with metal pieces 8, similar to those on the legs 7 and a corresponding rod 10, adapted to engage with the two racks 25, fixed to the board 2%. A rod 1 1 having arms 15 and rods 13, similar to the members 1 1, 15 and 13 respectively, are also provided for shifting the The sides 20 of the lower frame rest on the two angles 23, fastened to the sides of the base 1 and are held in place by the two blocks 22, one on each side of the frame. The table 3 is therefore adapted to slide along the base 1. The table 3 is locked in position by means of the rod 28, which engages with any one of the holes 27 in the bar 26, which is fixed to the base 1. The rod 28 is kept down by means of spring 30 pressing against collar 30, as shown in Fig. 3.

Referring to Figs. 1, 3 and 5, the horizontal bar 31, to which the traction straps are attached, is provided with recesses at its ends as shown, in order to prevent the straps from slipping off as the tension is alternately applied and released. The bar 31 is attached to the vertical bar 33, which is adjustably fixed to the frame 3 1 and is either square or rectangular in cross section, in order to prevent it from rotating. The frame at is fixed to the two racks 35, which are held in place by the guide bars 36 and the separating blocks 37. The gears 38, fixed to the shaft 39, mesh with the racks 35. The pawls e1 are adapted to engage with the ratchets 10 which are fixed to the shaft '39, and thereby lock the ratchets against rotation when the traction straps The removable crank arm 42 is used to rotate the shaft 39 in either direction and thereby the position of the frame 36% and the bar 31 can be shifted.

The worm wheel as is rotatably mounted on the frame 14:, which is fixed to the cross bar 48 and meshes with the worm a5, fixed to the shaft 416. The shaft 46 is also connected to the shaft of the motor 4:7 and is driven by it. The motor is supported on the cross bar 19. The adjustable crank rod 50, is pivotally fixed at one end to the worm wheel 43 and at the other end to the rocker 51. The latter is pivotally fixed to one end of the rod 52, while its upper end is either square or rectangular in cross section and is 60- to receive the horizontal traction adapted similar in form to the bar 31. The

bar 31 bar-52 is also either square or rectangular in cross section and passes through the socket piece 53, fixed to the side 5" of the upper frame of table 2. The side of the bar 52 is provided ends of same are hooked over the recesses 32 in the traction bar 31. Another set of straps are passed around the waistlof the patient and the ends of same are hooked over the bar 31. The table is then adjusted at the various points as previously described until the patient is in the position desired. The motor 17 is then started. This causes the bar 51 to rock and in turn the tension on the straps is alternately applied and re- 7 leased.

Having thus described my invention, I
